Meet the Inventors Obama Highlighted in the State of the Union

2 minute read

President Obama called for the renewal of the “spirit of discovery” that’s embedded in America’s DNA in his state of the Union address on Tuesday night.

“We’re Thomas Edison and the Wright Brothers and George Washington Carver,” he said, noting the inventors of the lightbulb, the airplane, and the man who made use of the peanut.

“We’re Grace Hopper and Katherine Johnson and Sally Ride,” he said.
